NECO2 IS GROWING

Since launching in August 2025, NECO2 has published 4,772 product carbon data entries, supporting more consistent embodied carbon assessments across Aotearoa New Zealand.

Developed by BRANZ and CIL Masterspec, NECO2 is the only MBIE-endorsed project for a national carbon repository. It replaces previous static spreadsheets with a maintained, regularly updated dataset, standardised for New Zealand use.

The repository includes major updates from earlier BRANZ data, with thousands more entries and refined assessment methods to support greater trust, consistency, and transparency in embodied carbon reporting.

NECO2 is helping build a shared data foundation for the construction sector — connecting manufacturers, specifiers, designers, LCA practitioners, tool providers, and policy makers through one national reference dataset.
